Re-programmable secure device

ABSTRACT

A re-programmable wireless device can store data securely and use near field communication (NFC) to exchange functionality data and/or program code from a central server system through a mobile device. A user requests a new re-programmable wireless device or a new re-programmable wireless device function via an application on the mobile device. The central server system transmits program code and a public key used to identify the re-programmable wireless device to the mobile device, which functions as a pass-through conduit for the information, storing it until the devices are synced. A NFC communication channel is created, and the mobile device authenticates the re-programmable wireless device by cross-referencing the public key received from the central server system with the public key transmitted by the re-programmable wireless device once the communication channel is established. Upon authentication, the re-programmable wireless device is synced with the mobile device, and the mobile device passes the program code to the re-programmable wireless device.

CROSS REFERENCE TO RELATED APPLICATIONS

This patent application claims priority to and is a continuation of U.S. patent application Ser. No. 14/061,727, filed Oct. 23, 2013 and entitled “Re-Programmable Secure Cryptographic Device.” The entire contents of the above-identified priority application are hereby fully incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates generally to cryptographic devices, and more particularly to methods and systems that allow users to re-program wireless devices that can store data securely and use radio frequency (RF) communication to exchange functionality data.

BACKGROUND

Wireless device technology incorporates proximity communications between two devices to authenticate and enable the transfer of data (for example, payment information) over the air or without physical connection. Near Field Communication (NFC) is an example of a proximity communication option that can enable wireless device communications and that is supported by the Global System for Mobile Communications (GSM) Association. NFC communication distances generally range from about 3 to about 4 inches. Such short communication distances enable secure communication between close field proximity enabled devices.

In GSM phones, a proximity-enabled controller (for example, an NFC controller) with an antenna is incorporated into the wireless device with the secure contactless software applications located on a smart chip. An NFC-enabled wireless device enables the transfer of data information to a reader device to enable financial transactions, ticketing, secure authentication, coupons, and other transaction for the device owner.

SUMMARY

In certain example aspects described herein, a method for providing a re-programmable wireless cryptographic device comprises a re-programmable wireless cryptographic device that can store data securely and use near field communication (NFC) to exchange functionality data and/or program code from a central server system, high security module cloud system, or other third part system through a portable communication device (for example, a user's mobile phone). The user accesses an account management system application on a mobile device and requests a new user device via the account management system application on the mobile device. The mobile device transmits the request to the account management system. The account management system transmits program code and an identifier used to identify the user device to the mobile device, which functions as a pass-through conduit for the information, storing the information until the user device syncs with the mobile device. The user device is brought within a predefined proximity of the mobile device or otherwise “tapped” with the mobile device, and an NFC communication channel or other form of proximity based wireless communication channel is created. The mobile device authenticates the user device by cross-referencing the identifier received from the account management system with the identifier transmitted by the user device once the communication channel is established. Upon authentication, the user device is synced with the mobile device and the mobile device passes the program code to the user device.

The user submits a request for a new user device function via the account management system application on the mobile device. The mobile device transmits the request to the account management system, and the account management system authenticates the user device. Upon authentication, the account management system transmits program code for the desired functionality to the mobile device. The mobile device saves the program code until it syncs with the user device. Upon syncing with the user device, the program code is transmitted to the user device via a wireless communication channel.

These and other aspects, objects, features, and advantages of the example embodiments will become apparent to those having ordinary skill in the art upon consideration of the following detailed description of illustrated example embodiments.

DETAILED DESCRIPTION OF THE EXAMPLE EMBODIMENTS

Overview

The example embodiments described herein provide computer-implemented techniques for providing a re-programmable wireless cryptographic device that can store data securely and use near field communication (NFC) to exchange functionality data. In an example embodiment, the re-programmable wireless cryptographic device is a smart card, wristband or bracelet, key fob, or other wireless token or device that does not comprise an operating system, an application host processor, an internal power source, or a user interface. In an example embodiment, the re-programmable wireless cryptographic device receives program code from a central server system, high security module cloud system, or other third part system through a portable communication device (for example, a user's mobile phone).

For example, the re-programmable wireless cryptographic device may be a bracelet device worn by hospital patients. The bracelet is programmed to include the patient's medical data. Additional functionality may be programmed onto the bracelet to allow the bracelet to function as a door access pass, to track medications given to the patient, and other functionality as required. In another example, the re-programmable wireless cryptographic device is a smart card. The smart card is programmed to include payment information for the user's Issuer A VISA account. The user then adds functionality to the smart card to include payment information for the user's Issuer B MasterCard account and security access for the user's place of business. The smart card retains the functionality of the user's Issuer A VISA account, until the user removes that functionality.

The user accesses an account management system application on a mobile device. In an example embodiment, the account management system maintains an account for the user and comprises programs encoding functionality that may be added to the user's re-programmable wireless cryptographic device. The user requests a new user device via the account management system application on the mobile device, and the mobile device transmits the request to the account management system. In an example embodiment, the user device is the re-programmable wireless cryptographic device. The account management system transmits program code and an identifier used to identify the user device to the mobile device. In an example embodiment, the mobile device does not have access to a private key required to read or otherwise understand the program code. In this embodiment, the mobile device functions as a pass-through conduit for the information, storing the information until the user device syncs with the mobile device.

The user device is brought within a predefined proximity of the mobile device or otherwise “tapped” with the mobile device, and an NFC communication channel or other form of proximity based wireless communication channel is created. The mobile device authenticates the user device by cross-referencing the public key received from the account management system with the identifier transmitted by the user device once the communication channel is established. Upon authentication, the user device is synced with the mobile device and the mobile device passes the program code to the user device. In an example embodiment, the user device comprises the private key and is capable of reading and otherwise understanding the program code. The user device transmits a successful formatting message to the mobile device, and the mobile device displays the message on the user interface. In an example embodiment, the program code is received by and processed in a secure element resident in the user device.

The user submits a request for a new user device function via the account management system application on the mobile device. The mobile device transmits the request to the account management system, and the account management system authenticates the user device. Upon authentication, the account management system transmits program code for the desired functionality to the mobile device. The mobile device saves the program code until it syncs with the user device. Upon syncing with the user device, the program code is transmitted to the user device via a wireless communication channel. In an example embodiment, the user adds or removes additional functionality to the user device by repeating this process.

In an alternative example, the account management system can initiate the change of device function for the user device by communicating the program code for the desired function to the mobile device. The mobile device then communicates the program code for the desired function to the user device when the user device next syncs with the mobile device.

In an example embodiment, the user device transmits use data to the mobile device while the devices are synced. The mobile device transmits the use data to the account management system but is unable to read or otherwise understand the data.

The inventive functionality of the invention will be explained in more detail in the following description, read in conjunction with the figures illustrating the program flow.

Example System Architectures

Turning now to the drawings, in which like numerals indicate like (but not necessarily identical) elements throughout the figures, example embodiments are described in detail.

FIG. 1 is a block diagram depicting a re-programmable wireless cryptographic device system, in accordance with certain example embodiments. As depicted in FIG. 1, the exemplary operating environment 100 comprises a user device 110, a mobile device 120, an account management system 130, and a device reader 150 that are configured to communicate with one another via one or more networks 140. In another example embodiment, two or more of these systems (including systems 110, 120, 130, and 150) are integrated into the same system. In some embodiments, a user associated with a device must install an application and/or make a feature selection to obtain the benefits of the techniques described herein.

Each network 140 includes a wired or wireless telecommunication means by which network systems (including systems 110, 120, 130, and 150) can communicate and exchange data. For example, each network 140 can be implemented as, or may be a part of, a storage area network (SAN), personal area network (PAN), a metropolitan area network (MAN), a local area network (LAN), a wide area network (WAN), a wireless local area network (WLAN), a virtual private network (VPN), an intranet, an Internet, a mobile telephone network, a card network, Bluetooth, near field communication network (NFC), any form of standardized radio frequency, or any combination thereof, or any other appropriate architecture or system that facilitates the communication of signals, data, and/or messages (generally referred to as data). Throughout this specification, it should be understood that the terms “data” and “information” are used interchangeably herein to refer to text, images, audio, video, or any other form of information that can exist in a computer-based environment.

In an example embodiment, each network system (including systems 110, 120, 130, and 150) includes a device having a communication module capable of transmitting and receiving data over the network 140. For example, each network system (including systems 110, 120, 130, and 150) may comprise a server, personal computer, mobile device (for example, notebook computer, tablet computer, netbook computer, personal digital assistant (PDA), video game device, GPS locator device, cellular telephone, Smartphone, or other mobile device), a television with one or more processors embedded therein and/or coupled thereto, or other appropriate technology that includes or is coupled to a web browser or other application for communicating via the network 140.

In an example embodiment, the mobile device 120 may be a personal computer, mobile device (for example, notebook, computer, tablet computer, netbook computer, personal digital assistant (PDA), video game device, GPS locator device, cellular telephone, Smartphone or other mobile device), television, or other appropriate technology that includes or is coupled to a web server, or other suitable application for interacting with web page files. The user can use the mobile device 120 to program, format, and/or re-program the user device 110 via a user interface 121 and an application 125. In an example embodiment, the user communicates with the account management system 130 via the application 125 to obtain program code for the user device 110. In another example embodiment, the user communicates with the user device 110 via the application 125 to format and reprogram the user device 110. The application 125 is a program, function, routine, applet or similar entity that exists on and performs its operations on the mobile device 120. For example, the application 125 may be one or more of a user device 110 application, account management system 130 application, an Internet browser, a digital wallet application, a loyalty card application, another value-added application, a user interface 121 application, or other suitable application operating on the mobile device 120. In some embodiments, the user must install an application 125 and/or make a feature selection on the mobile device 120 to obtain the benefits of the techniques described herein.

In an example embodiment, the mobile device 120 obtains data from the user device 110, stores the data in the data storage unit 127, and transfers the data to the account management system 130. In an example embodiment, the mobile device 120 is unable to understand the data received from the user device 110.

In another example embodiment, the user device 110 receives program code from the account management system, a central server system, high security module cloud system, or other third part system through the mobile device 120. In this embodiment, the mobile device 120 obtains data encoding a functionality for the user device 110 from the account management system 130, stores the data in the data storage unit 127, and writes the data to the user device 110 to provide the user device 110 with additional functionality. In an example embodiment, the mobile device 120 is unable to understand the data received from the account management system 130.

An example mobile device 120 comprises a secure element 129 or secure memory, which can exist within a removable smart chip or a secure digital (SD) card or which can be embedded within a fixed chip on the device 120. In certain example embodiments, Subscriber Identity Module (SIM) cards may be capable of hosting a secure element 129, for example, an NFC SIM Card. The secure element 129 allows a software application 125 resident on the device 120 and accessible by the device user to interact securely with certain functions within the secure element 129, while protecting information stored within the secure element 129. The secure element 129 comprises applications running thereon that may perform the functionality described herein. In an example embodiment, the secure element 129 comprises components typical of a smart card, such as crypto processors and random generators. In an example embodiment, the secure element 129 comprises a NFC controller in a highly secure system on a chip controlled by a smart card operating system, such as a Java Card Platform operating system. In another example embodiment, the secure element 129 is configured to include a non-EMV type contactless smart card, as an optional implementation. The secure element 129 communicates with the application 125 in the mobile device 120. In an example embodiment, the secure element 129 is capable of storing encrypted user information and only allowing trusted applications to access the stored information. In an example embodiment, a controller 123 interacts with a secure key encrypted application 125 for decryption and installation in the secure element 129.

Additionally, the secure element 129 also may comprise secure software applications, such as payment applications, secure forms of the applications 125, authentication applications, payment provisioning applications, user device 110 programming applications, secure data transfer applications, or other suitable application using the secure functionality of the secure element 129.

In an example embodiment, the data storage unit 127 and application 125 may be implemented in the secure element 129 on the mobile device 120. In another example embodiment, the data storage unit 127 may be a separate memory unit resident on the mobile device 120. An example data storage unit 127 enables storage of user contact details for retrieval of a user account management system 130 account and user device 110 program code. In an example embodiment, the data storage unit 127 can include any local or remote data storage structure accessible to the mobile device 120 suitable for storing information. In an example embodiment, the data storage unit 127 stores encrypted information, such as HTML5 local storage.

The mobile device 120 communicates with the user device 110 via an antenna 124. When the mobile device 120 has been activated and prioritized, the controller 123 is notified of the state of readiness of the mobile device 120 for a transaction. The controller 123 polls through the antenna 124 a radio signal, or listens for radio signals from the user device 110.

An example user device 110 is a re-programmable secure cryptographic device, such as a smart card, wristband or bracelet, key fob, or other wireless token or device that does not comprise an operating system, an application host processor, an internal power source, or a user interface.

The user can use the user device 110 to perform a programmed function via an application 115. For example, the user device 110 may be a bracelet device worn by hospital patients. The bracelet is programmed to include the patient's medical data. Additional functionality may be programmed onto the bracelet to allow the bracelet to function as a door access pass, to track medications given to the patient, and other functionality as required. In another example, the user device 110 is a smart card. The smart card is programmed to include payment information for the user's Issuer A VISA account. The user then adds functionality to the smart card to include payment information for the user's Issuer B MasterCard account and security access for the user's place of business. The smart card retains the functionality of the user's Issuer A VISA account, until the user removes that functionality.

An example user device 110 comprises a secure element 119 or secure memory, which can exist within a removable smart chip or a secure digital (SD) card or which can be embedded within a fixed chip on the device 110. In certain example embodiments, Subscriber Identity Module (SIM) cards may be capable of hosting a secure element 119, for example, an NFC SIM Card. The secure element 119 allows a software application 115 resident on the device 110 and accessible by the device user to interact securely with certain functions within the secure element 119, while protecting information stored within the secure element 119. The secure element 119 comprises applications running thereon that may perform the functionality described herein. In an example embodiment, the secure element 119 comprises components typical of a smart card, such as crypto processors and random generators. In an example embodiment, the secure element 119 comprises a NFC controller in a highly secure system on a chip controlled by a smart card operating system, such as a Java Card Platform operating system. In another example embodiment, the secure element 119 is configured to include a non-EMV type contactless smart card, as an optional implementation. The secure element 119 communicates with the application 115 in the user device 110. In an example embodiment, the secure element 119 is capable of storing encrypted user information and only allowing trusted applications to access the stored information. In an example embodiment, a controller 113 interacts with a secure key encrypted application 115 for decryption and installation in the secure element 119.

Additionally, the secure element 119 also may comprise secure software applications, such as payment applications, secure forms of the applications 115, authentication applications, payment provisioning applications, secure data transfer applications, or other suitable application using the secure functionality of the secure element 119.

In an example embodiment, the data storage unit 117 and application 115 may be implemented in the secure element 119 on the user device 110. In another example embodiment, the data storage unit 117 may be a separate memory unit resident on the user device 110. An example data storage unit 117 enables storage of user contact details for retrieval of a user account management system 130 account and/or authentication of the user device 110. In an example embodiment, the data storage unit 117 can include any local or remote data storage structure accessible to the user device 110 suitable for storing information. In an example embodiment, the data storage unit 117 stores encrypted information, such as HTML5 local storage.

The user device 110 communicates with the device reader 150 via an antenna 114. When the user device 110 has been activated and prioritized, the controller 113 is notified of the state of readiness of the user device 110 for a transaction. The controller 113 polls through the antenna 114 a radio signal, or listens for radio signals from the device reader 160.

An example device reader 150 comprises an application 155. A device reader operator can use the device reader 150 to read or retrieve information from the user device 110 via the application 155. The application 155 is a program, function, routine, applet or similar entity that exists on and performs its operations on the device reader 150. For example, the application 155 may be one or more of a user device 110 application, account management system 130 application, a payment application, a ticketing application, an access code application, a data retrieval application, an Internet browser, a digital wallet application, a loyalty card application, another value-added application, or other suitable application operating on the device reader 150. In some embodiments, the device reader operator must install the application 155 and/or make a feature selection on the device reader 150 to obtain the benefits of the techniques described herein.

An example mobile device 120 also communicates with the account management system 130. An example account management system 130 comprises an account management module 133 and a data storage unit 137. In an example embodiment, the user creates an account with the account management system 130. The account management module 133 manages the registration of the user. Regarding user account registration, the account management module 133 may generate web-based user interfaces providing forms for the user to register for an account management system 130 account. For example, the account management module 133 can collect basic user identifying information, registration information on one or more user devices 110, registration information on one or more mobile devices 120, and payment information. In an example embodiment, the user registers one or more financial accounts, including bank account debit cards, credit cards, gift cards, a link to a proxy for one or more financial accounts (for example, a digital wallet link where the digital wallet is connected to other payment accounts), or other type of financial account that can be used to make a purchase, with the account management system 130 using the account management module 133. In an example embodiment, the registered financial payment information may be used to complete a purchase by the user with a merchant system operating the device reader 160. In an example embodiment, the user account information is stored in a user account or is otherwise associated with the user in the data storage unit 137.

In an example embodiment, the data storage unit 137 can include any local or remote data storage structure accessible to the account management system 130 suitable for storing information. In an example embodiment, the data storage unit 137 stores encrypted information, such as HTML5 local storage.

The components of the example-operating environment 100 are described hereinafter with reference to the example methods illustrated in FIGS. 2-7. The example methods of FIGS. 2-7 may also be performed with other systems and in other environments.

Example System Processes

FIG. 2 is a block flow diagram depicting a method for providing a re-programmable wireless cryptographic user device 110, in accordance with certain example embodiments. The method 200 is described with reference to the components illustrated in FIG. 1.

In block 210, a user accesses an account management system 130 application 125 on a mobile device 120. In an example embodiment, the user downloads or otherwise enables the account management system 130 application 125 on the mobile device 120 to perform the functions described herein. In an example embodiment, the user accesses the application 125 by opening or enabling the application 125.

In block 220, the account management system 130 receives notification that the user accessed and/or enabled the application 125 on the mobile device 120 and determines whether the user has an account management system 130 account. In an example embodiment, the user is prompted to long into or create an account management system 130 account when the application is enabled. In another example embodiment, the user previously logged into the account management system 130 account and is otherwise automatically logged into the account. In yet another example embodiment, the user's login credentials are shared across other accounts (for example, social networking websites and mobile device 120 accounts) and the user is automatically logged into the account management system 130 account using the shared login credentials.

If the user does not have an account management system 130 account, the method 200 proceeds to block 230 and the user is prompted to create an account management system 130 account. In an example, the user is prompted to register with the account management system 130 when the user accesses the application 125. In another example embodiment, the user is prompted to register with the account management system 130 when the user downloads or enables an application 125. In yet another example embodiment, the user is not required to log in or register for the account management system 130 account. In this embodiment, the methods described herein are performed for a “guest” user.

In an example embodiment, the account management system 130 account is a digital wallet account maintained by the account management system 130 or a third party system. In another example embodiment, the user may use a smart phone application 125 to register with the account management system 130. In yet another example embodiment, the user accesses the account management system 130 via a smart phone application 125.

From block 230, the method 200 proceeds to block 240 in FIG. 2.

Returning to block 220 in FIG. 2, if the user has an account management system 130 account, the user logs into the account in block 235. In an example embodiment, the user's account management system 130 account information is saved in the mobile device 120 and the user is automatically signed into the user's account management system 130 account. In another example embodiment, the user is automatically logged into the account management system 130 account using shared login credentials. In yet another example embodiment, the user was previously logged into the account management system 130 account and is not required to login.

In block 240, the user submits a request for a new a re-programmable wireless cryptographic user device 110 via the account management system 130 application 125 on the mobile device 120. In an example embodiment, the user is prompted to login or create an account management system 130 account when submitting a request for a new user device 110. In an example embodiment, the user requests an initial function and/or functions to be performed by the device 110 and a user device 110 type or design when requesting the new user device 120. For example, the user can request that the user device 110 is a bracelet that is capable of maintaining patient records or a fob tag that is capable of acting as a door access card.

In block 250, the new user device 110 is formatted. The method for formatting a new re-programmable wireless cryptographic user device 110 is described in more detail hereinafter with reference to the methods described in FIG. 3.

FIG. 3 is a block flow diagram depicting a method 250 for formatting a new re-programmable wireless cryptographic user device 110, in accordance with certain example embodiments, as referenced in block 250. The method 250 is described with reference to the components illustrated in FIG. 1.

In block 310, the mobile device 120 submits the request for the new user device 110 to the account management system 130. In an example embodiment, the account management system 130 application on the mobile device 120 directs the mobile device 120 to communicate with the account management system 130 and transmit the request for the new user device 110 to the account management system 130. In an example embodiment, the mobile device 120 transmits an account identifier that corresponds to the user's account management system 130 account when submitting the request for the new user device 110. In an alternative example embodiment, the mobile device 120 stores the request for the new user device 110 until the mobile device 120 is capable of communicating with the account management system 130.

In block 315, the account management system 130 receives the request for a new user device 110 from the mobile device. In an example embodiment, the account management module 133 receives the request. In an example embodiment, the account management system 130 identifies the user account that corresponds to the account identifier transmitted with the request for a new user device 110.

In block 320, the account management system 130 creates a public/private key pair for the new user device 110. In an example embodiment, the public key is understandable by the mobile device 120 and is used by the device 120 to identify the user device 110 when the devices (including devices 110 and 120) are synced. In this embodiment, each user device 110 has a unique or different public key or device 110 identification understandable by the mobile device 110 that is used to request the user device 110 and the account management system 130. In an example embodiment, the public key is a use device 110 identifier or account management system 130 account identifier. In another example embodiment, the mobile device 120 does not identify or authenticate the user device 110. In an example embodiment, the private key is maintained by the account management system 130 and is not understandable by the mobile device 120. In an example embodiment, the mobile device 120 does not have access to the private key. In this embodiment, the private key is required to read or otherwise understand the program code transmitted by the account management system 130. In this embodiment, the mobile device 120 functions as a pass-through conduit for the information, storing the information until the user device 110 syncs with the mobile device 120. In an example embodiment, the private key and public key pair are known to the user device 110 and the account management system 130.

In block 330, the account management system 130 saves the public and private keys for the user device 110. In an example embodiment, the public and private keys are saved in the user's account management system 130 account.

In block 340, the account management system 130 retrieves program code for the user device 110 and transmits the information to the mobile device 120. In an example embodiment, the program code is required to activate and enable the user device 110. In another example embodiment, the program code comprises code to enable one or more initial functions of the user device 110. In this embodiment, the one or more initial functions correspond to the functions requested by the user when requesting the new user device 110. In an example embodiment, the program code is retrieved from the data storage unit 137. In an example embodiment, the program code comprises the user device 110 identifier or key.

In block 345, the mobile device 120 receives the program code and device 110 identifier for the new user device 110. In an example embodiment, the account management system 130 application 125 receives the program code and device 110 identification from the account management system 130.

In block 350, the mobile device 120 saves the program code and device 110 identifier for the new user device 110. In an example embodiment, the information is saved by the application 125 in the data storage unit 127 until the user device 110 is synced with the mobile device 120.

In block 360, the account management system 130 identifies the user device 110 that comprises the same device 110 identifier that was transmitted to the mobile device 120.
